Study sheds light on why diabetes drug causes edema

In related discoveries with far-reaching implications for treating diabetes and understanding hypertension, University of Utah researchers have learned why thiazolidinediones (TZDs), a major anti-diabetes drug, cause edema and also have found a new pathway critical to fluid metabolism. Identification of this pathway may help understand fundamental mechanisms of blood pressure control. more
